MACHINE FOR RED-UCING WIRE.

' SPECIFICATION forming part of Letters Patent No. 428,572, dated May20, 1890.

Application led August 5 1889.

To all whom it may concern:

Be it knownthat I, FREDERICK A. PECK, a citizen of the United States,residing at Providence, in the State of Rhode Island, have invented anew and useful Improvement in Machines for Reducing Wire, of which thefollowing is a specification.

My invention'relates to that class of wirereducing machines in which the.reducingdies are operated by rapid contact withbeaters 5 and itconsists in the improved construction and arrangements of parts wherebythe machine is made adapted for a greater range of work than heretofore.

Figure l represents a plan 'view of my improved machine. vation of thesame. Fig. 3 is a longitudinal section. Figs. 4, 5, and 6 are detailviews.

In the accompanying drawings, A is the bedplate of the machine, and B abearing-standard secured to the forward end of the bed A and providedwith the friction-cap B', and at the rear end of the bed A is securedthe bearing-standard O, provided with the f riction-cap C. Within thebearing d of the standard B is placed the beater-holding head D, whichis also loosely held upon the hollow arbor E, the said arbor beingsupported at its rearward end in the bearing b of the' standard C, andupon the arbor E is secured` the pulley F. The head D is also providedwith a pulley D', and the pulleys D and F are each provided with araised rim d, having upon its periphery a screw thread or worm e, andalso provided with the annular groove f. The worm e of the pulley Fengages with a worm-gear G,

which is secured upon an upright shaft h, held by a sliding bar I, andhaving at its lower end a slotted crank-arm I-I, provided with anadjustable crank-pin z', the lower end of the said f.

crank-pin being held in the fixed groove j. The sliding bar I issupported in a horizontal position by means of the standards g g, and isprovided with an attached arm J, which enters the groove f of thepulley, so that when the sliding bar I is moved in either direction bythe action of the crank-pin in the Xed groove j the pulley F and arbor Ewill be correspondingly moved.

The worm e of the pulley D engages with the worm-gear G which is securedto an upright shaft h and held by the sliding bar I-,

Fig. 2 represents a side ele- Serial No. 319,806. (No model.)

arm II', provided with an adjustable crankpin 71, the lower end of thesaid crank-pin being held in the fixed groove j. The sliding bar I issupported in a horizontal -position by means of the standards g g', andis provided with an attached arm J which enters the groove f of thepulley D', so that when the sliding bar I is moved in either directionby the action of the crank-pin fr" in the fixed groove j the pulley Dand the head D will be correspondingly moved upon the arbor E and withinthe bearing d of the standard. The cylindrical rollers K K, which arepreferably employed for the beaters, are made of hardened steel, and areinserted into a conically-inclined series of holes m, made in the end ofthe head D, and are retained in their places for operation and rotationby means of the annular plate 7c, which is secured to the head D bymeans of the screws a.

Upon the forward end of the hollow arbor E is secured the hollow headE', which is provided with radial openings o o, adapted to receive thereducing-dies M M M M, which are retained in the openings o by means ofthe annular plate 7c', which is secured to the head E by means of thescrew n', and when 'the dies are thus inclosed in the openings o bymeans of the plate 7c they are adapted to be thrown outward by means ofsprings p, inserted in the rear portion of the head E and project-ingforward into the opening q at the rear end of the die, las shown in thesection, Fig. 5, and the dies M M are provided with the inclined facesd2, which are adapted to engage with the correspondingly-inclinedengaging-surface Z22 of the beaters K.

Upon the sliding rod L, which is supported bythe standards B and O,issecured the arm N, provided at its upper end with a steel bushandhavingat its lower end a slotted cranking r, for guiding the wire to thereel, and a by means of the standards B and C, is secured IOO the arm Q,which by means of a projecting arm is also supported by and slides uponthe sliding rod L, and at the upper end of the arm Q are placed thegrooved rolls R R, for feeding the wire through the machine. Upon theshaft of the lower feeding-roll R is secured the ratchet-wheel S, andupon the same shaft is placed the atchet-arm T, to which theratchet-catch u is pivoted, the said catch being held in contact withthe ratchet-wheel. by means of the spring n', and the ratchet-arm T isheld in its backward position against its adj listing-screw by means ofthe spring y. Upon the sliding rod O is also secured the arm l, theupper end of which is provided with the roller t, held in the groove fof the pulley F, so that the arm P, rod O, arm Q, and feeding-rolls R Rwill be made to partake of the reciprocating movement of the die-head E.In the operation of the machine, whenever it is desired to reduce thesize of round wire the beaterholding head D is to be clamped and heldstationary by screwing down the cap B and then upon revolving the pulleyF the arbor E and die-head Ewill revolve therewith, and the action ofthe worm e of the pulley F upon the worm-gear G will cause therevolution of the crank ll, and the consequent reciprocation of thedie-head E', within the beater-head D, and as the diehead E is carriedonward the inclined position of the beaters K K will allow the dies toopen outward to receive a new length of wire, which length of wire willbe reduced in size as the head E is being drawn back within the head Dby the continued action ofthe crank Il, the dies M M being carriednearer and nearer to each other until the head E has reached its innerlimit, and then the continued action ol the crank ll will again carrythe head E forward, causing the dies to open, so as to receive anotherlength of wire, and when the head E is moving forward the same movementwill be transmitted to the arm Q, which carries the feeding-rolls R R',and thus the wire being operated upon will partake of the reciprocatingmovement of the head E', and when the arm Q nears the limit of it-soutward movement the ratchet-arm 'll will strike the end of the screw.5' upon the arm N, thus causing the proper feeding movement ot therollsR R. \Vhenever it is vdesired to operate upon square or angularwire, then the arbor E is to be clamped in its proper fixed position bymeans of the cap C, and the head D loosened by unscrewing the cap B.Then upon revolving the head D by means of the pulley D the dies M Mwill be operated at a iixed position with reference to the wire, and theaction of the worm c upon the worm-gear G will cause the revolution ofthe crank Il', and the consequent reciprocation of the beater-head D andthe inclined beaters K K, whereby at the outward movement ot the head Dthe dies M M will be brought gradually nearer to each other, and uponthe reverse movement of the head D they will again separate from eachother to allow the feeding of the wire Vforward for another operation ofthe dies, and the required feeding movement ot the rolls R R will beeffected by means of the arm N, which partakes of the reciprocatingmovement oi the head D, and the adjusting-screw s' of which is made tostrike the ratchet-arm T.

lleretofore in machines of this class the beaters have been set withtheir engagingfaces parallel to the axis of the beater-holding head, allsuch machines being restricted in their range of work, and not adaptedfor self-feeding; but by arranging the engagingfaces of the beaters atan angle with the axis of the beater-holding head I am enabled by meansof a reciprocating movement imparted to either of the heads to graduallyclose the dies upon the wire while the beating action is going on, andto open the dies to receive another length of wire, which is fedforward, thus adapting the machine for automatic action and for agreater range of work than heretofore, and the inclination of theengaging-face of the beaters,as speciiied,constitutes the gist of myinvention, and is the foundation principle of the machine.
